Meeting: June 14, 2016

Subject: Approving Bid Award for the Pavement Lifting & Stabilization with Polyurethane Foam – South Locust St from Lake St. to Diversion Bridge

Presenter(s): John Collins PW, Public Works Director

Background

This project consists of lifting/leveling the concrete pavement and filling voids underneath with polyurethane foam. This will reduce the unevenness of the pavement both laterally and longitudinally creating a smoother ride and better drainage; existing condition pictures shown in Attachment 2.

The existing concrete is in good enough condition that the treatment can be used on the entire stretch of roadway. We usually remove and replace only the damaged panels, which does little to correct the ride or the drainage. A full panel replacement project is estimated to cost over $600,000.

Other benefits of pavement lifting with polyurethane foam include: Extending pavement life by reducing fractures caused by panel movement. Low traffic disruption since the work can be performed with lane closures. Short duration work compared to concrete removal and replacement. The entire

pavement lifting project should take about the same amount of time as it takes for concrete to cure.

The short work schedule reduces the need for traffic control and the use of existing pavement eliminates the need to re-stripe, further reducing costs.

Special provisions for this project state the work is to be completed by August 19, 2016. This completion date will avoid any work being performed during the Nebraska State Fair.

PolyLEVEL AdvantagesLightweight – PolyLEVEL weighs approximately 4-6 pounds per cubic foot when installed, which is significantly less than the 120 pounds per cubic foot of typical fill material. This means there is almost no additional load added to the supporting soils.

High Capacity – Lifting action is a result of the expansion of the polymer, allowing for lift on much higher loads than typical mudjacking that relies on hydraulic pressure being contained under a slab.

Accurate Lift – Calculated reaction time of the PolyLEVEL foam allows for a targeted, precise lifting operation.

Waterproof – PolyLEVEL is fully waterproof so it cannot washout. In addition, because it cannot take on water, it is not impacted by freeze/thaw cycles. Additionally, PolyLEVEL can be used to under-seal slabs and stop a variety of infrastructure leaks.

Non-Invasive – The equipment used to install PolyLEVEL can be used in extremely limited access areas, is far less messy than other methods, and can be installed more quickly.

Cure Time – Quick cure time allows for immediate loading, even heavy traffic, within 15 minutes after injection.

Compressive Strength – The in-place compressive strength of commercial grade PolyLEVEL material is minimally 11,000 pounds per square foot, and often exceeds 15,000 pounds per square foot.

Consolidates Soil – As PolyLEVEL foam exerts the energy to lift a slab, it is placing an equal amount of pressure on the soil beneath the slab. This process not only fills the void and raises the slab, but also densifies the soil below.

PolyLEVEL SystemThe Foundation Supportworks PolyLEVEL system utilizes high-density polymers to stabilize and level concrete. With multiple formulations available, PolyLEVEL is able to fit the needs of any job, large or small. PolyLEVEL is a two-part urethane polymer that expands into rigid, structural foam to fill voids, stabilize and lift concrete, and offer solutions to a wide range of geotechnical and structural applications. Polyurethane has been used beneath slabs for decades, and it has proven to be a superior solution compared to traditional methods of grout injection and concrete replacement.

PolyLEVEL Applications | Roads & Bridge ApproachesSettlement of highways and roadways is a problem that Departments of Transportation across the country are tasked with correcting on a regular basis. As expansion joint materials break down over time and allow water to penetrate below the slab, and the subgrade below the concrete compresses as a result of heavy traffic flow, sags often form in the roadway. These sags create difficult and unsafe driving conditions to the general public.

Bridge authorities face similar issues when dealing with the settlement and misalignment of bridge approach slabs. Often, these approach slabs are supported with backfill material which is both loose and poorly compacted. The stress and constant vibration the slab encounters during daily traffic compresses this fill material, thus creating voids below the concrete. As a result, many bridge approaches settle to the point where they are no longer within tolerance of what is considered a safe and acceptable gradient.

The PolyLEVEL system offers a long-lasting solution to repair sinking highways, roadways, and bridge approaches, while also providing many benefits that alternate options fail to achieve. While traditional methods of repair such as diamond grinding or removal and replacement of the concrete have been used in the past, these solutions are often temporary, cost prohibitive, time consuming, and fail to address the underlying cause of the problem - the soil beneath the slab. With the PolyLEVEL system, city and state agencies are able to correct the problem quickly, effectively, and with little inconvenience to the public. With its quick cure time, high compressive strength, and efficient installation, PolyLEVEL is often installed without having to completely shut down the roadway or bridge, allowing traffic to continue to flow without any major disruptions.
